ROTARY MINE-CAR DUMP.

Application filed December 22; 1927; SeriaTNo. 241,909.

The invention relates to mine car dumps otthe rotary type embodying a cradle to receive a car to be dumped, a weigh pan or other receiver under said cradle, and a coaliguide plate stationarily mounted atone side; of the cradle substantially concentric with sa d cradle and extending to said receiver: in dumps of this type, the coalin'the' car being dumped, is forcibly discharged against the coal guide plate, slides down the latter with increased velocity anl suddenly comes to rest in the receiver. against the coal guide plate and sudden arrest of its rapid descent, causes a great amount of breakage, and it is the'object 0t the'present invention to improve upon the construction of rotary dumps by the provision of novel means to permit the coal to move only gradually into contact with the coal guide plate and to prevent the coal from sliding from said plate until the coal reaches a point so close to the receiver that it cannot gain injurious momentum when released.

With the foregoing in view, theinvention resides in the novel subject matter hereinafter described and claimed, the description being accomplished by reference to the accompanying drawings.

Fig. 1 is a side elevation of a dump im'- proved in accordance with my invention.

Fig. 2 is an end elevation partly broken away showing the normal position of parts.

Fig. 3 is a duplicate of Fig.2 with the exception that it illustrates the action of the dump when inverting a car.

A dump is shown embodying the usual rotatable cradle 5 having supporting rails 6 for a mine car 7 and dogs 8 stationarilymounted above said rails to overlie the sides All of the parts so far described are well known and are illustrated only to disclose the Striking or". the coal manner in'which a dump embodying these parts lsimproved in accordance with my invent1on-..

I rigidly mount a coal check plate 15upon the cage 5, in position to extend longitudinall-y 01 and to project above one side 16 of the car 7, the-lower portion 17 'ofsaid plate 15, being substantially vertical, while its upper portion 18 is inwardly curved or is other- ,wise inwardly inclined beyond the plane 19 ofthe car side16, theupper edge oi said plate 15 being spaced from the cage anisiZO, a distance slightly less than the distance between said axis and the coal guide'plate'lt.

By mounting the plate 15 as above described, it receives the coal from the car 7 as the latter is dumped as seen in Fig. 3,? and it hence prevents torcibledischarge of the coal against the plate 14: and downward rushing of said coal with increased velocity until it comes to rest in the receiver 13, and consequently breakage of the coal is prevented. The plate15 holds the coal against contact with the guide plate It until the cradle: 5 and the car 7' have turnedsubstantially and eventhen the coal. can only gradually come in contact with said plate 14: so that there is no danger" of breakage. Moreover, the plate 15 supports the coal until it clears the lower end of the plate 14:, at which time discharge of coal into the receiver 13 takes place. Attention is here invited to the fact that at this time of final discharge into the receiverv 13, the point of discharge is so close to said receiver that the coal cannot gain sutlicient momentum to cause breakage thereof when it finally comes to rest. Hence, it will be seen that I have produced a distinct improvement over rotary mine dumps of the type to which this application is devoted.

In the preferred form of construction, the plate 15 extends longitudinally of and is anchored' to one of the dogs 8, and when this dog is constructed as'above described, I rivet or bolt the lower edge of said plate to the inner upstanding flange 21 of the upper channel bar 10, and to the outer upstanding flange 22 of said bar, I rivet or otherwise secure the lower ends of a plurality of braces 23, the upper ends of which are similarly secured to theupper portion of the plate 15. This construction utilizes old parts of the conventional mine dump, as a means to which to secure the plate 15 and its bracing means, and is consequently of advantage over other constructions which might be employed.

On account of the exist'ng advantages for the details disclosed, they are preferablyfollowed. However, within the scope of the invention as claimed, variations may be made.

' I claim 1- 1. In a rotary mine car dump embodying a cradle to receive a car to be dumped, a receiver under said cradle, and'a stationary coal guide plate at one side of the cradle, substant-ially concentric therewith and extending to said receiver; a coal check plate rigidly secured to said cradle in position to extend longitudinally of and to project above one side of a car in said cradle, saidcoal check plate having its upper portion inclined inwardly beyond the plane of said one car side and terminated a distance from the cradle axis slightly less than the distance between said axis and said coal guide plate; whereby said coal check plate will hold the coal from sliding against. said coal guide plate until the car has turned substantially ninety degrees, will then permit the coal to gradually slide against said coal guide plate and will then co-act with said coal guide plate to prevent dumping of the coal until said coal check plate travels be yond the lower end of said coal guide plate.

2. In a rotary mine car dump embodying a cradle having car-supporting rails and dogs extending longitudinally above said rails to overlie the sides of a car in the cage, anda stationary coal guide plate at one side of the cradle, substantially concentric therewith; a coal check plate secured to, extending longitudinally of and projecting upwardly from one of said dogs, said coal check plate having its upper portion inclined inwardly beyond the plane of the car side engaged by said one dog and terminated a distance from the cradle axis slightly less than the distance between said axis and said coal guide plate; whereby said coal check plate will hold the coal from sliding against said coal guide plate until the car has turned substantially ninety degrees, will then permit the coal to gradually slide against said coal guide plate and will then coact with said coal guide plate to prevent dumping of the coal until said coal check plate travels beyond the lower end of said coal guide plate.

3. In a rotary mine car dump embodying a cradle having car-supporting rails and dogs extending longitudinally above said rails to overlie the sides of a car in the cradle, at least one of said dogs having a channel bar secured along its upper. side with its flanges projecting upwardly, and a stationary coal guide plate at one side of the cradle substantially concentric therewith; a'coal check plate extending longitudinally of said channel bar and at its lower edge secured to the inner flangeoit said bar, said coal check plat-e projecting upwardly from said bar and having its upper portion inclined inwardly beyond the plane of said inner flange and terminated a distance from the cradle axis slightly less than the distance'between said-axis and said coal guide plate, and bracing means for said i coal check plate secured to the latter and secured to the outer flange of the aforesaid channel bar.

In testimony whereof I have hereunto at fixed my signature.

JOHN S. BEPKO.
